    Intel GMA graphics cards & OpenGL Extensions...

    Hi

    I'm trying to find a list of OpenGL capabilities & extensions available for various Intel graphics chips, but have been unable to locate any on the web.

    If anyone has the time/inclination I'd very much appreciate you downloading the following...

    http://delphi3d.net/hardware/glinfo2.zip (from delphi3d.net)

    ...and posting the results here. If you click on the 'Reports' button from the above, and then click 'Save Report', it will save an HTML file for you. If you can then copy the data from the table and post here I'd be forever in your debt!

    BTW - you don't need to install the software from the .zip file - just run the .exe it contains. You can then just delete it if you wish.

    Many thanks in advance
    Mark

    PS - Here's a sample from my graphics card...

    Hi,

    Just dl OpenGL extension viewer from http://www.realtech-vr.com/. It has a database for almost every card.

    Basically, you have shading language 1.2 with vertex, fragment and geomatry shaders, transform feedback, framebuffer blit etc. (alas, no floating-point textures yet). I don't think this will differ much for windows (as far as I know, floating-pint textures are supported on windows)

    Actually, I would be surprised if the Windows driver even has GLSL support.

    Re: Intel GMA graphics cards & OpenGL Extensions..

    Thanks Zengar...

    Best I can tell (hence me asking here) is that the intel windows drivers don't even support frame buffer objects! And I'd much rather have a simple render path - not use FBOs if they exist, else pBuffers etc.

    I'm doing an app which is seriously CPU bound, so it makes sense to move all GUI to an accelerated graphics card (there's quite a lot of GUI stuff going on). I've held off for GL3, but I'm loosing confidence in that... but that's another story.

    So, I've got to make a choice - either OpenGL or Direct3D. I really WANT* to use GL, but I'm concerned that many laptops will struggle with it - I need things like frame buffer object & GLSL. I may be forced down the D3D route though. Which sucks. Intel are totally pissing me off with their useless drivers - even more than Kronos ;-)

    *In an ideal world I'd like the potential to easily port to Mac and/or Linux, so I only use Win32 stuff to create windows (one for each monitor) which are essentially just surfaces on which to draw. I also use Win32 to handle mouse/keyboard, and create threads. This tiny amount of code should be trivial in a port.

    Na, the world is everything but ideal

    Is there any indication that intel will be improving their openGL drivers?

    Seeing as Intel are part of the decision making process regarding OpenGL's future, I think it's a totaly obvious answer...

    No.

    Intel are shite. A bunch of scumbags Intel are causing me no end of grief, simply because they don't know how to write drivers - their chipsets are [feature wise] quite adaquate for my purposes but they seem unable/unwilling to write GL drivers. Thank goodness they have a say about the future of OpenGL. Not.

    I apologise to Intel about my personal anguish over how they are single handedly forcing me to double my workload. STOP. Actually, I don't apologise at all - Intel really are shite

    I just dream of the day when we can use one 3D API (or in my case mostly 2D) on multiple platforms. Any intel employees reading this? Shoot yourselfs!!!! PLEASE!

    Sorry. End of rant.

    Re: Intel GMA graphics cards & OpenGL Extensions..

    It looks strange ... today's intel graphic processor support OpenGL 2.x ! I don't know it very well but I think that intel windows driver supports OpenGL 2.x if hardware is designed for OpenGL 2.x. If driver on Mac/Intel enables FBO, why windows/Intel can't do it ?

    I think the problem comes from the testing hardware and not from the intel driver. If you find any documentation on non-support OpenGL API of Windows Intel driver, I will be happy to read it

    Intel graphic processors are not so bad since MacOS works perfectly on it !

    I don't know how the Windows drivers are handled, but Apple did a significant amount of work on their Intel drivers, to "raise the bar" as much as possible, and support a common feature set (GLSL, FBO, etc) across all hardware vendors.

    There definitely are limitations to the Intel hardware though, which are difficult for the drivers to work around (CLAMP, multisample, float pixels...)
